I own a lamp and light fitting sales company called deslamps and am undergoing a website re-design. To go with the new website, I wish to take professional photographs of all of the light bulbs I am selling. I need the photographs to be uniform in exposure and colour, to keep it all uniform on the website.
I understand that I will need a digital SLR camera (prefably with a remote shutter switch), a tripod, a light cube and 2 external light sources (daylight bulbs).
I currently have a light cube and I am looking at buying the canon 400D camera. I have also seen a lot of people talking about editing the photos afterwards, but I dont think I will be able to do this, as I need every photo to be uniform, especially in the back ground colour.

Does anyone have any suggestions for any different cameras, and any information about the rest of the rig I need would be much appreciated.
